FIELD
[0002]
The present disclosure relates to the field of wireless communications, particularly to a wireless communication system in an electronic device, user equipment and method for wireless communication in a wireless communication system.
Background technique
[0003]
This section provides background information related to the present disclosure, which is not necessarily prior art.
[0004]
With the evolution of wireless networks, carrying more and more of service, thus requiring additional spectrum resources to support a large number of data transmission. Cellular wireless network operator on the basis of the network, began to explore how to use unlicensed spectrum resources such as 5GHz ISM (Industrial Scientific Medical, Industrial, Scientific and Medical) band using the existing LTE (Long Term Evolution, Long Term Evolution). On the other hand, WiFi wireless industry is also more WiFi system will be deployed in an unlicensed spectrum. Communication system between different operators and different systems have equal right to use the unlicensed band, so different operators and different systems in the use of unlicensed spectrum resources may cause interference, resulting in one of the information transmission failure.
[0005]
The WiFi system, the contention window (contention window, CW) is one of the effective solutions to resolve resource conflicts, the configuration of the data transmission sent during the contention window when the node needs to randomly select a random contention window as in the range of wait time, until the waiting time after the sending node to use the corresponding resources for data transmission. System spectrum management server may set the size of the contention window (contention window size, CWS) according to the size of the different needs of each transmitting node. Accordingly, when the size of the contention window size is relatively large, corresponding to the transmitting node using the unlicensed spectrum low probability; and when the size of the contention window size is relatively small, corresponding to the transmitting node using unlicensed spectrum probability. Does not support the contention window system, such as LTE system, a counter may be provided for each transmitting node, the contention window is similar to that role. A counter configured transmitting node during the data transfer, as the value of the counter needs to wait time, waiting time until after the sending node to use the corresponding resources for data transmission. Nodes of the network side, the base station may be, for example, the value of the counter for each sending node according to different needs. Thus, when the counter value is larger, the corresponding node transmitting unlicensed spectrum using low probability; and when the counter value is small, the corresponding transmitting node uses unlicensed spectrum probability.
[0006]
Further, during the use of unlicensed spectrum resources for transmission of information, if there is a node outside of the transmitting side is able to sense the scope of the information transmission, the transmitting end for this node is not visible, it is hidden node, then the transmission of information hidden nodes will be the sender of the information transmission causing interference, leading to transmission failure information. To solve this problem, the transmitting side can reduce energy detection threshold, the transmitting side to expand the sensing area, so that the transmitting side is able to sense a hidden node and to monitor it.
[0007]
In an unlicensed band pass node operating in a wireless communication system carrying out information transmission, the transmitting side may change due to channel quality information between the receiving terminal generates transmission fails, the receiving side may have suffered previously described generating interference information transmission failed hidden node or from other access mechanisms. In the case where the reasons for the changes due to channel quality between the transmitter and the receiver to generate failure information transmission, spectrum sensing parameter adjustment, e.g. contention window size or value of the counter is clearly unreasonable, so how we can know the reason for the failure information transmission it is particularly important.
[0008]
Therefore, it is necessary to provide a new wireless communication technology solutions, so that the information can be acquired transmission failure reason, and only when the failure cause information transmission spectrum sensing parameters non-adjusted if the link quality reasons, to improve the transmission side between the receiving end and the probability of successful transmission of information, and to avoid unnecessary adjustment.

[0036]
Referring now to the drawings more fully described examples of the present disclosure. The following description is merely exemplary in nature and not intended to limit the present disclosure, application, or uses.
[0037]
Providing the exemplary embodiments so that this disclosure will be thorough, and will fully convey the scope to those skilled in the art. Numerous specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of embodiments of the present disclosure. Those skilled in the art it will be apparent that the specific details are not required to use, the exemplary embodiments may be embodied in many different forms, they should not be construed as limiting the scope of the present disclosure. In certain exemplary embodiments, there is no known procedure described in detail, well-known structures and techniques are well known.
[0038]
The present disclosure relates to a UE (User Equipment, user equipment) including but not limited to mobile terminals, computers, vehicle-mounted equipment terminal having a wireless communication function. Further, depending on the specific features described, the present disclosure relates to the UE itself, the UE may also or chip components therein. Further, similarly, the base station of the present disclosure may be involved, for example, eNB (evolution Node Base Station, an evolved node base station) or the eNB chip components.
[0039]
FIG 1 (a) is a schematic diagram from a hidden node, or interference from other access mechanisms illustrating a downlink transmission exists when according to a wireless communication system according to the present embodiment of the disclosed embodiments. As shown in FIG 1 (a), the memory UE1-UE5, eNB can transmit the uplink information and downlink information transmission and the UE is in the coverage of the eNB. When the eNB transmits downlink data to UE1, AP (Access Point, AP) is located outside the detection range of the energy from the eNB UE1 also at a position close to the transmission data. Since the AP is located outside the detection range energy eNB, the eNB does not know there is an AP, the AP does not know whether the transmission data. In other words, AP can be seen as a hidden node. Here, AP is also possible from other operators or other access mechanism. Thus, when the UE1 data reception, receives the data from the eNB, also receive data from the AP, in this case, data from the AP on the UE1 causing interference.
[0040]
FIG 1 (b) is a schematic diagram from a hidden node, or interference from other access mechanisms according to the presence of illustrating uplink transmission when the radio communication system according to embodiments of the present disclosure. FIG 1 (b), the memory UE1-UE5, eNB can transmit the uplink information and downlink information transmission and the UE is in the coverage of the eNB. When the UE1 sends uplink data to the eNB, AP (Access Point, AP) located at a distance outside the detection range of the energy UE1 eNB close position data are transmitted. Since the AP is located outside the detection range energy UE1, UE1 and therefore does not know there is an AP, the AP does not know whether the transmission data. In other words, AP can be seen as a hidden node. Here, AP is also possible from other operators or other access mechanism. Thus, when the eNB receives the data, receives data from the UE1, also receive data from the AP, in this case, data from the AP to the eNB causing interference.
[0041]
In FIG. 1 (a) scene shown in (b) and FIG. 1, when the transmission of information between the UE1 and the eNB fails, there may be several reasons: poor link quality between the eNB and UE1; from Hide interfering node AP; interference from other carriers or access mechanism. In the conventional method, the receiving side can not know the reason UE1 eNB or transmission failure information, and therefore may make inappropriate adjustment. The basic principles of the present invention is the transmitting side can be informed of the reason or cause of the failure information transmission failures of information transmitted, and adjusted according to different reasons, in order to increase the probability of transmitting side and receiving side between a successful information transmissions.
[0042]
To solve the above technical problem, a technical solution of the present disclosure. FIG 2 illustrates the structure of a wireless communication system according to the present embodiment of the disclosed embodiment of the electronic apparatus 200.
[0043]

[0044]
Further, the processing circuit 210 may include a variety of discrete functional units to perform various functions and / or operations. Incidentally, these functional units may be physical or logical entities, and the different names may be realized by means of the same physical entity.
[0045]
For example, as shown in Figure 2, the processing circuit 210 may include an acquisition unit 211 and the generator 212.
[0046]
It represents a NACK information transmission between a wireless communication system transmitting and receiving ends and transmitting the information representing failure cause of the failure cause of the failure information of the present embodiment disclosed embodiments, acquisition unit 211 may acquire, wherein the information transmission failure reason is classified as non-link link quality reasons and quality reasons.
[0047]
Here, the acquisition unit 211 may receive from the transmitting end of a wireless communication system NACK information and cause of failure information, may be received NACK information and cause of failure information from the receiving end of a wireless communication system, it may also be from a wireless communication system transmitting end or receiving end receives information related to the cause of the failure, by the processing circuit 210 (e.g., the analysis unit, not shown) to analyze the cause of the failure. After that, the acquisition unit 211 may transmit failure cause information indicating a transmission failure reason to the information generation unit 212.
[0048]
According to the present embodiment of the present disclosure, when it is determined that the information transmission failure cause is not a link quality reasons, the generation unit 212 may generate a spectrum sensing parameter information, to adjust the transmitting side spectrum sensing parameters, in order to improve the transmission of information between the end and the receiving end transmission probability of success.
[0049]
Here, the generating unit 212 may acquire the Failure information 211 from the acquisition unit, and may be generated in a transmission spectrum sensing parameter information directly or indirectly to the transmitting side, the transmitting side to adjust the spectrum sensing parameters.
[0050]
The electronic device using the embodiment of the present disclosure 200, such reasons can be known between the transmitter and the receiver of the transmission failure information, and link quality reasons when adjusting the transmitting end only when the reason for the failure information transmission spectrum sensing parameters non , whereby the adjustment can be avoided when a transmission failure cause information is spectrum sensing parameters link quality reasons, to improve the probability of transmitting side and receiving side between a successful information transmissions.
[0051]
According to an embodiment of the present disclosure, the spectrum sensing parameters includes energy detection threshold, and counters contention window size.
[0052]
According to the present embodiment of the present disclosure, when the cause of the failure determination information transmission link quality reasons, the electronic device generating unit 200 212 can also generate control information to adjust the transmitting side MCS (Modulation and Coding Set, modulation and coding combination) and open loop link adaptation parameters.
[0053]
Spectrum management server 200 may be a core network in accordance with an embodiment, the electronic device of the present disclosure. The transmitting end may be a UE or eNB, the receiving end may be a UE or eNB. Electronic device 200 can also be located in eNB.
[0054]
Next will be divided into downlink transmission and uplink transmission are described in detail according to the present disclosure the electronic apparatus 200 of the embodiment.
[0055]
Downlink transmission
[0056]
FIG 3 is a schematic diagram illustrating a signaling interaction embodiments of the present disclosure will be downlinked. 3, the electronic device 200 may be a core network spectrum management server, the eNB is the transmitting side, the receiving end is a UE. First, eNB transmits downlink data to the UE. Subsequently, UE side generates a transmission failure. At the UE side, will analyze the downlink transmission failure cause information to analyze the reason for the failure is the downlink information transmission link quality reasons or reasons for non-link quality. Subsequently, UE transmits feedback information to the eNB, for example, information indicating the NACK information transmission fails. In addition, UE also indicates the reason the transmission failure information to the information transmission failure reason eNB. Next, eNB fails to forward information to the reasons for spectrum management server. Subsequently, when the acquisition unit 211 acquires the cause of the failure spectrum management server, if the reason for the failure is determined is not a link quality reasons, the spectrum management server generating unit 212 generates a spectrum sensing and parameter information transmitted through the communication unit 220 eNB. Next, eNB perceptual spectrum sensing parameters to adjust the parameter information according to the received spectrum.
[0057]
According to the present embodiment of the present disclosure can be used to represent one bit of information cause of the failure information, e.g., the corresponding bit is "1" indicates that the link quality reasons; the corresponding bit is "0" means a non-link quality reasons. In addition, UE can use PUSCH (Physical Uplink Shared Channel, physical uplink shared channel) and / or PUCCH (Physical Uplink Control Channel, a physical uplink control channel) channel transmission failure cause information. For example, when it is desired transmission failure cause information, UE has uplink data to be transmitted, the UE may carry the uplink data using PUSCH, NACK and the reasons for failure; when required transmission failure cause information, UE no uplink data to transmit, the UE may use PUCCH carries an uplink data, and the reasons for failure NACK; further, in order to save the resources of the PUCCH, the UE can also be used to carry the cause of the failure PUSCH, the PUCCH to carry the NACK.
[0058]
According to an embodiment of the present disclosure, may include a reason for the link quality non disturbed hidden nodes and the receiving end from the surrounding interference from other carriers or access mechanism.
[0059]
Represents presence or absence of the hidden node information hidden node embodiment of the present disclosure, the acquisition unit 211 of the electronic device 200 may also be obtained according to. When the information indicating the presence of hidden nodes hidden nodes, such that the spectrum generating section 212 generates the parameter information is possible to reduce perceptual transmission end detection threshold energy, so that the transmission side can sense a hidden node.
[0060]
According to the present embodiment of the present disclosure, the UE not only to analyze the cause of the failure information transmission link quality is a cause or a non-link quality reasons, it is possible to analyze the link quality non disturbed because of hidden nodes around the receiving end from still subject to interference from other operators or access mechanism. Here, the UE can be detected by methods known in the art whether there exist hidden nodes, and then analyze the cause of two or more non-link quality. E.g., UE Wifi communication system by detecting a beacon (Beacon), or other operators detected reference signal and PLMN (Public Land Mobile Network, Public Land Mobile Network) identifier to determine whether the presence of hidden nodes. Of course, the UE may further detect whether some other manner by the presence of hidden nodes, which is not defined in the present disclosure.
[0061]
According to one embodiment of the present disclosure, when a UE analyze the cause of the failure information transmission is not a link quality reasons, we can be actively continue to analyze what kind of non-specific link quality reasons. Next, UE can also indicate whether the UE exists around the hidden nodes to send information to eNB. Here, two bits of information can be represented cause of the failure information, e.g., bits corresponding to "10" indicates the link quality reasons; the corresponding bits are "00" indicating the presence of hidden nodes around the UE, the corresponding bit "01" indicates that the UE does not exist around the hidden nodes, the reason for the failure by operators or interference from other access mechanism, the corresponding bits are "11" for other reasons.
[0062]
According to another embodiment of the present disclosure, when downlink data transmission, when the UE analyze the cause of the failure information transmission is not a link quality reasons, can only report the cause of the failure to a non-eNB link quality reasons, and then wait for the eNB further instructions. That is, when the spectrum management server receives the link quality indicates a non-Failure Cause reason, the processing circuit 210 may send commands to the eNB 220 through the communication unit to instruct the UE to sense whether the presence of hidden nodes around the UE. Next, eNB forwards the command to the UE. Subsequently, when the UE receiving the command, continuing to analyze what kind of non-specific link quality reasons. When the UE around an analyzed for the presence of hidden nodes, indicating whether UE can transmit information about the presence of hidden nodes UE to the eNB. Here, one bit of information may be used to indicate whether there is a hidden node, e.g., the corresponding bit is "1" indicates the presence of hidden nodes; the corresponding bit is "0" indicates the absence of the hidden node.
[0063]
According to the present embodiment of the present disclosure, when the failure reason indicates the presence of hidden nodes around the UE, spectrum management server generates the spectrum sensing parameters may include reducing the eNB energy detection threshold, and the reduced energy detection threshold sent to the eNB, so that the eNB can energy detection range is expanded, and thus find the hidden nodes around the UE. After that, the eNB may also perform other operations, such as monitoring the hidden nodes and the like.
[0064]
According to the present embodiment of the present disclosure, the cause of failure when the UE does not exist around represents hidden nodes, i.e., the reason of failure when the transmission of information by the operator or interference from other access mechanism, the processing unit 212 generating circuit 210 generates a spectrum sensing parameters spectrum sensing information so that the value of the parameter information can be increased contention window size or counter eNB.
[0065]
According to the present embodiment of the present disclosure, when the eNB side arranged contention window, spectrum management server may increase the size of the contention window eNB, and transmits the increased contention window size to the eNB, so as to reduce the chance eNB corresponding access frequency; when the eNB side arranged counters, spectrum management server may increment the counter of the eNB, and transmits the counter value to increase the eNB, so as to reduce the chance of access eNB corresponding frequency. Here, the counter value of the contention window size, and the access latency eNB indicates certain frequency.
[0066]
According to the present embodiment of the present disclosure, in a case where the probability of successful transmission of information between the transmitting end and the receiving end is increased, the processing circuit 210 is further configured to perform the following operations: after a predetermined period of time, generating a command to restore the transmission end of the spectrum sensing parameters.
[0067]
Here, when the eNB spectrum sensing parameters are adjusted later, data transmission can continue eNB and the UE. That is, after each successful transmission of information, the UE will transmit feedback information indicating successful ACK message to the eNB; information after each transmission fails, the UE will represent the feedback information NACK message transmission failure and reason for the failure to eNB. The eNB may send the ACK / NACK information to the spectrum management server. Next, the spectrum management server can determine whether the probability of a successful transfer of information between eNB and UE is increased according to the ACK / NACK information. For example, within a predetermined period of time, the account number of the data in whole ACK ACK and NACK and the ratio is larger than a predetermined threshold value, the spectrum management server that the probability of successful transmission of information between the eNB and the UE is increased. In this case, the processing circuit 210 generation unit 220 may generate a spectrum sensing parameters, to recover the eNB spectrum sensing parameters. For example, the eNB to improve the energy detection threshold, reduce the size of the contention window eNB or decrease the value of the counter.
[0068]
According to another embodiment of the present disclosure, the processing circuit 210 is further configured to perform the following operations: after a predetermined period of time, generating a command to restore the transmitting side spectrum sensing parameters. Here, spectrum management server regardless of whether the probability of successful transmission of information between eNB and UE is increased, all in after a predetermined period of time, generating spectrum sensing parameters, in order to restore the perception of the spectrum eNB parameters.
[0069]
Acquiring the plurality of pieces of a predetermined period of time and cause of failure information NACK information; and the cause of the failure is not a link quality information indicating the cause of the transmission failure reasons: according to embodiments of the present disclosure, the processing circuit 210 is further configured to perform the following operations the number of information representing the number of NACK information ratio, determining information transmission failure cause is not a link quality reasons.
[0070]
In this embodiment, the eNB and the UE may be multiple transmissions of data, every time the information transmission failure occurs, a UE will NACK feedback information and cause of failure information to the eNB, that is, each corresponds to a NACK message the reason. In the electronic apparatus 200 side (e.g. analyzing unit, not shown), and you can count the number of the total number of link quality non cause failure cause NACK information over time, and calculating the number of non-data link quality reasons accounts NACK information proportion. Next, the electronic device 200 (e.g. analyzing unit, not shown) to determine the cause of the failure is not a link quality information transmission ratio calculated based on the reason. For example, when the data causes a non-link quality information representing the number of NACK ratio is larger than a first threshold value, that the reason for non-link quality information transmission failure reason; when the ratio data causes a non-link quality information representing the number of NACK equal to or less than a first threshold value, that the reason for the failure information transmission link quality reasons.
[0071]
According to another embodiment of the present disclosure, the processing circuit 210 is further configured to perform the following operations: acquiring a plurality of pieces of information transmitted between NACK information and cause of failure information showing a plurality of transmission and reception ends in success within a predetermined period of time the ACK information; and a link quality based on information indicating a transmission failure reason the proportion of the number of number of non-link quality reasons cause failure cause information representing NACK and ACK information and to determine the cause of the failure information transmission non.
[0072]
In this embodiment, the electronic device 200 side (e.g. analyzing unit, not shown), can count the number of the total number of ACK information over time, the total number of non NACK information and reasons for the failure of link quality reasons, and calculates data link quality non causes the proportion of the number of ACK information and NACK information and the. Next, the electronic device 200 (e.g. analyzing unit, not shown) to determine the cause of the failure is not a link quality information transmission ratio calculated based on the reason. For example, when the number of data causes a non-link quality information and the ACK NACK account information and a range of greater than a second threshold value, that the reason for non-link quality information transmission failure reason; when the link quality data causes a non-accounted NACK the number of information and the ACK information and the ratio is less than or equal to the second threshold value, that the reason for the failure information transmission link quality reasons.
[0073]
Example embodiments of the present disclosure, the electronic device 200 may determine the cause of the failure in the failure reason according to the ratio of the predetermined period of time is indeed occupied by non-link quality reasons, thus avoiding the cause inaccurate analysis according to the UE side, so that the failure reason analysis more precise.
[0074]
The foregoing description, in the downlink transmission in the eNB and the UE, when the cause of the non-failed transmission link quality reasons, UE side can be analyzed by the UE interference from surrounding hidden node or by the operator or from other interfering access mechanism. According to another embodiment of the present disclosure, when the reason for the failure is not a link transmission quality reasons, the network side, i.e., the electronic device 200 side can also analyze the cause of the failure information is transmitted in the two reasons which .
[0075]
To perform operations according to embodiments of the present disclosure, the processing circuit 210 is further configured to: Data link quality or a non-proportional number of reasons for the failure reason for the number of non-link quality information based on the accounting reasons NACK and ACK information and accounting the number of NACK information and the ACK information and the ratio to determine whether there is a hidden node; when present hidden nodes, such that the spectrum sensing parameter information can be reduced transmitting side energy detection threshold, so that the transmission side is able to sense the hidden node; and when when hidden node does not exist, so that the spectrum sensing information parameter value can be increased contention window size or counter on the transmitting side.
[0076]
According to one embodiment of the present disclosure, as described above, the electronic device 200 side (e.g. analyzing unit, not shown), count the number of NACK may be a period of time the total number of link quality and the reason for non-failure cause information and calculates data representing the non-link quality reasons the number of NACK information ratio. Next, the electronic device 200 (e.g. analyzing unit, not shown) to determine the cause of the transmission failure information is present around hidden nodes UE based on the calculated ratio. For example, when the data causes a non-link quality information representing the number of NACK ratio is larger than the third threshold value, a transmission failure cause information that is present around hidden nodes the UE; when the ratio data causes a non-link quality information representing the number of NACK greater than the first threshold value and equal to or less than the third threshold value, that the reason for the failure information transmitted by the UE interference from other carriers or access mechanism.

[0085]
According to an embodiment of the present disclosure, the eNB can analyze not only the failure cause information is transmitted link quality reasons or reasons of non-link quality is also possible to analyze the link quality non disturbed because of hidden nodes around the receiving end from still subject to interference from other operators or access mechanism. Here, the eNB by methods known in the art, such as energy sensing method to analyze two or more non-link quality reasons.
[0086]

Then, eNB can send the ACK / NACK information and the reasons for failure to spectrum management server. Next, the spectrum management server can determine whether the probability of successful transmission of information between the UE and eNB is increased according to the ACK / NACK information. For example, within a predetermined period of time, the account number of the data in whole ACK ACK and NACK and the ratio is larger than a predetermined threshold value, the spectrum management server that the probability of successful transmission of information between the UE and the eNB is increased. In this case, the processing circuit 210 generation unit 220 may generate a spectrum sensing parameters, the UE to recover the spectrum sensing parameters. For example, to increase the energy detection threshold of the UE, reducing the size of the contention window UE or decrementing the counter value.
